You control a messiah with WASD, and you can thrown lightnings by clicking. On a randomly generated little island, you will be able to transform the environment and lead your little tribe, that will evolve in a way or another. With a little chance, your pairs will become workers, and a small society will develop. Or maybe some of them will prefer to become animals ? Or will they revolt against you and try to put you on a cross ?
It's a sandbox game I think, you'll have to try many times to succed to make something with it...
I suggest you read this article to understand a little better (maybe) : http://www.ludumdare.com/
